San Holo

He uses Serum at 6:12 as a swell pad and at 17:29 he clearly shows some instances of the synth frozen in Ableton.

San Holo can be seen using massive at 2:18

At 3:35 he says he used Kontakt for some sitar-like sounds in his song 'One Thing' "I used Kontakt for this stuff." "I bounced the MIDI track so my computer doesn't glitch"

He uses this plugin for bitcrush/distortion effect, clearly seen at 12:37

Developed in collaboration with San Holo. Some of the samples were extracted directly from his song “Light”, hence the pack’s name.

He uses SoundToys' EchoBoy for delays, clearly stated at 10:08 You can also see an instance of the plugin at 11:42 in another track, so I think he uses this plugin quite often.

He uses this plugin for volume automation on the lead sound in 'One thing' (13:40). He does however sidechain with Ableton's compressor and added the VolumeShaper for extra movement.

He uses this effect on his guitar to give it a warpy wobbly effect (18:53)

35:30, he is using it for the bass sound in Light

In the Cymatics.fm workshop, San Holo uses the IK Multimedia Classic T-RackS Multi-band Limiter as a plugin on the master channel of his track "Light."

In the Cymatics.fm workshop, San Holo discusses using iZotope Ozone 9 as the final plugin on his master channel for the track "Light." He mentions pushing the limiter extensively since everything is sidechained to his kick and snare, allowing for greater headroom. Additionally, he applies stereo spread to the mids and highs. Note: The source initially mentioned Ozone 8, but it is Ozone 9.

States that he loves this reverb and used it on the main vocal in “light” at 12:06

At 17:16 (and many other times in the video) you can see on his Tracklist M1, and in his AU folders you can see one of the developers ois Korg, which I assume means he used the M1 VST.

7:32 you can see the channel strip he used to make the main sound in “Light”
